As we all know, there are many different methods for the synthesis of a compound, and people can choose the synthesis method that suits their own laboratory according to the actual situation. 13423-60-4 name is 1-Phenyl-1H-1,2,4-triazole, This compound is widely used in many fields, so it is necessary to find a new synthetic route. The downstream synthesis method of this compound is introduced below. 13423-60-4

To 10 mL of chlorosulfonic acid at 0 C was added 1 g (6.9 mmol) of1-phenyl-1H-1,2,4-triazole, 35. The mixture was stirred overnight andthen cooled to 0 C. The solution was slowly added to ice and extracted3 three times with dichloromethane. The organic layers were combined,dried over sodium sulfate and concentrated to dryness in vacuo to give1 g of a tan solid. The crude sulfonyl chloride was used directlywithout further purification. To a microwave vial was added 25 mg(0.095 mmol) of the sulfonyl chloride, 15 mg (0.11 mmol) of 1,2,3,4-tetrahydroquinoline, 14 mg (0.014 mmol) of triethylamine and 300 muLof acetonitrile. The vial was sealed and heated at 130 C for 30 min. Themixture was diluted with dichloromethane and the organic phase waswashed 2 times with water and brine. The organic layer was dried oversodium sulfate and concentrated in vacuo. The crude sulfonamide waspurified by flash chromatography 0-75% EtOAc/Hexanes.
